AI Holders Summary · Q1 2026

Microsoft registers 5,965 institutional filers holding roughly $1.97 trillion in combined 13F value, making it the most valuable single stock in the institutional universe. The latest quarter sends mixed signals: BlackRock trimmed about $71.5B, Soroban Capital launched a brand-new $23.5B position, and State Street expanded, underscoring that even at Microsoft scale active managers still make dramatic quarter-over-quarter bets.

The passive core moved in both directions. BlackRock remains the single largest holder at roughly $219.7B but DECREASED by approximately 8.9M shares, trimming notional value by about $71.5B this quarter. State Street INCREASED by roughly 2.4M shares, adding $34.5B. FMR/Fidelity DECREASED by roughly 10.7M shares while JPMorgan DECREASED by approximately 20.6M shares ($25.8B). These are real portfolio decisions at the largest institutional platforms, likely responding to Azure growth reacceleration, Copilot monetization visibility, and capital-allocation credibility.

Soroban Capital Partners LP is the standout active signal. The firm filed a brand-new position of roughly $23.5B, up from nearly zero in the prior quarter. A ~63.6M share launch in a concentrated value and event-driven strategy signals deliberate conviction rather than mandate-driven passive demand.
